CCC 2017: Continuity, Computability, Constructivity – From Logic to Algorithms, Nancy (France), June 26 – 30, 2017

CCC is a workshop series bringing together researchers from exact real number
computation, computable analysis, effective descriptive set theory,
constructive analysis, and related areas. The overall aim is to apply logical
methods in these disciplines to provide a sound foundation for obtaining exact
and provably correct algorithms for computations with real numbers and related
analytical data, which are of increasing importance in safety critical
applications and scientific computation.

Previous workshops have been held in Cologne 2009, Trier 2012, Gregynog 2013,
Ljubljana 2014, and Kochel 2015. The conference series has always been linked
with EU-funded international research projects,  with COMPUTAL (Computable
Analysis) in the years 2012-2015 and now with CID (Computing with Infinite
Data), a research network between Europe, Chile, Japan, New Zealand, Russia,
Singapore, South Africa, South Korea, and the USA. This conference is the first
CID event, but is open to all researchers in the area.

The workshop will take place in Nancy, France.


The workshop specifically invites contributions in the areas of

  • Exact real number computation,
  • Correctness of algorithms on infinite data,
  • Computable analysis,
  • Complexity of real numbers, real-valued functions, etc.
  • Effective descriptive set theory
  • Scott’s domain theory,
  • Constructive analysis,
  • Category-theoretic approaches to computation on infinite data,
  • Weihrauch degrees,
  • And related areas.

Invited Speakers:

  • Matthew de Brecht (Kyoto, Japan)
  • Bernhard Reus (Brighton, UK)
  • Matthias Schröder (Darmstadt, Germany)
  • Alex Simpson (Ljubljana, Slovenia)


Extended abstracts (1-2 pages) of original work are welcome.
